Tronox Incorporated Becomes Independent Company; Thomas W. Adams Named Chairman and Chief Executive Officer

OKLAHOMA CITY, March 31 /PRNewswire-FirstCall/ -- Tronox Incorporated marked its first day as an independent company today, following the completion of the distribution by Kerr-McGee Corp. of its shares of Tronox Incorporated Class B common stock to Kerr-McGee shareholders. Tronox Incorporated Class A common stock is traded on the New York Stock Exchange under the ticker symbol "TRX" and Class B common stock is traded under "TRX.B."

As announced on March 28, the Tronox board of directors has named Thomas W. Adams chairman and chief executive officer, succeeding Robert M. Wohleber, Kerr-McGee senior vice president and chief financial officer, who resigned as chairman and a director of Tronox in connection with the distribution.

"Tronox is well positioned to capture future opportunities through a value strategy focused on increasing cash flow, profits and returns," said Adams, chairman and chief executive officer. "We have the right people and the right assets in place, and now we must execute on our strategic plan. Recognizing that aligning our employees with our strategy is essential to our success, we have introduced a new employee incentive program with specific targets for cash flow, net income, return on invested capital, quality, uptime and cost reductions. In addition, many of our employees became Tronox shareholders when, in connection with the distribution, Tronox stock-based awards were issued to employees who held Kerr-McGee stock-based awards, providing these employees with further motivation to increase shareholder value.

"I commend our employees around the world for their continued commitment to Tronox and their tireless efforts to successfully complete our transition to a stand-alone company," said Adams. "I also want to thank Kerr-McGee's board of directors and employees, in particular Kerr-McGee Chairman and Chief Executive Officer Luke Corbett, and Kerr-McGee officers and former Tronox board members Bob Wohleber and Mike Rauh for their support and assistance throughout the separation process.

"On behalf of Tronox's board, officers and employees, I welcome our new shareholders who are joining us as a result of the distribution," said Adams. "I encourage you to learn more about Tronox through our website or by calling our investor relations department. We are excited about our future and focused on increasing the value of your investment in our company."
